GRAIN-GAR-IDOOR CLOSURE.

Specification of Letters Patent.

Patented Nov. 2?, 121% Application filed June 19, 1916. Serial No.104,414.

To all whom it may concern:

Be it known that I, JAMES A. MCNULTY, a citizen of the United States,residing at Kansas City, in the county of Jackson and State of Missouri,have invented a certain new and useful Improvement in Grain-Car- DoorClosures, of which the following is a full, clear, concise, and exactdescription, reference being had to the accompanying drawings, forming apart of this specification.

This invention relates to grain car door closures.

The object of the invention is to provide an improved nailless graindoor for railway cars having adjustable means adapting the door to dooropenings of different widths and this invention is in the nature of animprovement on the structure disclosed in the patent granted to James A.McNulty, 1,143,219, dated June 15, 1915.

More specifically, the main object of the invention is to provide animprovement in the means for retaining the adjustable hook or attachingelement in any of its adjusted positions; to cheapen the cost ofapplication of the adjustable attaching element; and to facilitate thesecuring of the attaching element in any position.

I11 the drawing forming a part of this specification, Figure 1 is a sideelevation of a portion of a car showing the improved nailless grain doorapplied thereto. Fig. 2 is a horizontal sectional view of the structureillustrated in Fig. 1 and taken substantially on the line 22 thereof.Fig. 3 is a vertical sectional view of the structure illustrated in Fig.1 and taken on the line 33 thereof. Fig. 4 is a horizontal sectionalview upon an enlarged scale, illustrating more particularly theadjustable hook and parts directly associated therewith, the sectionbeing taken on the line 4.4 of Fig. 1. Fig. 5 is a vertical sectionalview of the structure illustrated in Fig. 4 and taken on the line 55thereof. Fig. 6 is a vertical sectional view taken substantially on theline 66 of Fig. 4:, and Fig. 7 is a detailed perspective of the slidablemember which carries the hook or attaching element.

In said drawing, 10 denotes the side wall of the car having the usualdoor opening 11, threshold 12, side posts 13-13 and lintel 1 1. Theimproved nailless grain door is preferably made in three sections A, Band G arranged one above the other and having improvements in theirmeeting edges ship-lapped as indicated in Fig. 3. The sections A, B andC are formed of boards extending horizontally, the same being cleatedand battened as necessary to provide the requisite strength. The lowersection A is provided with a grain relief door 15 as shown in Fig. 1.Each of the sections A, B and G is pro vided at one end with anattaching element such as the hook 16, the latter being mounted on asuitable eye 17 and the hook being adapted to be driven into theadjacent post. Each of the sections A. B and C is provided at itsopposite end with an adjustable attaching element, more particularlyhereinafter described. The general arrangement of the parts as abovedescribed is substantially the same as that disclosed in said Patent1,143,219.

The adjustable attaching element which, as shown herein, comprises ahook 18 is also adapted to be driven into the adjacent side post 13, asclearly indicated in Figs. 2 and 4. It will be understood by thoseskilled in the art, that other forms of attaching elements may beemployed. The hook 18 is provided with an eye 19 at its inner end whichis threaded through an openin 20 in a carrier plate or casting 21. Themain portion of the carrier 21 extends outwardly from andperpendicularly to the door section by which it is carried, therebypermitting the hook 18 to be swung upwardly and downwardly as may benecessary to pull the door section to tight engagement with the doorpost. The carrier 21 is provided on its inner portion with three sets ofoppositely extended feet or projections 22, the sets being separatedlongitudinally of the carrier equal distances for the purposeshereinafter described. The carrier 21 is slidably mounted within alongitudinally extending slot 23 cut in a plate 24. secured to the outerface of the door section, by screws 25 or other suitable means. Theplate 2 1, except for short portions near its ends, is corrugated withthe corrugations extending vertically as clearly indicated in Fig. 4 at26 and 27, the corrugations 26 extending outwardly and the corrugations27 inwardly. These corrugations 26 and 27 are formed in the plate 2 1both above and below the slot 23. As will be understood from examinationof Fig. 4, the distance from center to center of the corrugations 2626and from center to center of the corrugations 27-27 correspond to thedistance between the sets of projections or feet 2222 on the carrier 21.lhe plate 2 11s counter-sunk into the door section so that its outersurface lies flush with the ment of the carrier 21 relatively to theplate 2 1. As clearly appears from Fig. 4L, the feet or projections 22are adapted to engage in any set of the recesses formed on the rearsides of the corrugations 26 so that the carrier 21 may be adjusted toany desired position. It will also be apparent that, when the book 18 isdriven into the adjacent door post with the feet 22 lodged in recessesformed by the corrugations, the tension occasioned by the hook beingdriven home will hold'the carrier 21 in its adjusted position.

As an additional means of holding the carrier 21 in any desiredposition, a wedge 29 has been provided which is slidably mounted in aslot 30 formed in the carrier '21. The wedge 29 at its lower end isflattened as indicated at 31 to thereby prevent accidental removal ofsaid wedge after the parts have been assembled. The slot 30 is locatedmidway between two of the sets of the feet 2222 so that, when thecarrier is in proper position, the wedge 29 may be forced downwardly andwill engage in the recess formed between two of the corrugations 26-2G,as clearly illustrated in Figs. 4 and 5.

As clearly shown in the drawing, the cleats 32 on the left-hand ends ofeach of the members A, B and C are adapted to engage the adjacent sidedoor post and thus prevent the door members from slipping toward theleft, as viewed in Fig. 1. On the other ends of the members A, B and C,the carriers 21 will be adjusted as closely as po sible to thecorresponding adjacent side door post and thus effectively preventslipping or" thedoor members to the right, as viewed in Fig. 1. In orderto provide proper clearances for the hooks and eyes 16 and 17 and toprevent the same from getting jammed or distorted when the door membersare arranged in piles, the cleats 32 are provided with semi-circularrecesses 33 as indicated in Fig; 1, said recesses beingof suflicientsize to permit thehooks to fall completely therewithin when the hooksare not in use.

- The parts are assembled by first inserting the wedge 29 in the slot 30after which the carrier 21 is slipped into the slot 23 of the plate 2 1,it being noted that the slot 23 is open at the left-hand end of theplate as viewed in Fig. 5. The plate 2-1:, carrier 21 and wedge 29 beingthus assembled, the plate 2 1 is then permanently attached to the doorsection. From the foregoing description, it will be seenthat thearrangement provided is simple; the plate 2 1 may be cheaplymanufactured from sheet metal by a stamping operation; two cooperatingsets of means are provided for holding the car rier 21 in adjustedposition; and the adjust-- ment may be easily and quickly made to adaptthe door sections to difierent widths of door opening.
